Beyond 1080p screens - Path to 4K uncertain for Oculus?

How does Oculus move beyond 1080p in the next 2 years, considering that :

1) OLED seems to be the only tech that can achieve low persistence.
2) Samsung is the leading technology producer of high PPI small OLED panels.

*and most importantly*

3) According to reports, even Samsung are struggling to produce 2K screens for the S5 and are allegedly moving to Sharps LCD production capability to help out. (and as a side note, their 1080p panels were pentile, to help them cram the pixel density).

http://www.phonearena.com/news/Samsung-Galaxy-S5-might-have-a-2K-LTPS-display-made-by-Sharp-AMOLED-on-the-backburner_id50997

The questions then become:

1) What is the path to Oculus Rift moving to 2K and beyond over the next 2 years?
2) Are there any forms of competing technology that have OLED like response times, that can legitimately be used in Oculus? (rear Lazer projection? CRT !!? :lol:)


excerpt from wiki

http://en.wikipedia.org/wiki/OLED

Response time
OLEDs also can have a faster response time than standard LCD screens. Whereas LCD displays are capable of between 1 and 16 ms response time offering a refresh rate of 60 to 480 Hz, an OLED theoretically can have a response time less than 0.01 ms, enabling a refresh rate up to 100,000 Hz .[citation needed]. OLEDs also can be run as a flicker display, similar to a CRT, in order to eliminate the sample-and-hold effect that creates motion blur on OLEDs.[63]

    CRTs cant' be fit into small and lightweight (and low-power for that matter) applications, so that's no, although CRTs themselves are fine.

    Laser projector seems good option - infinite resolution, sharp colors, no screendoor, minimum persistence. It also doesn't require large or high power units, and particularry, it could be fit on the inside of display screen rather than on the outside. One serious drawback is narrow laser frequency band that has to be dealt with, it imposes requirements for ridiculously high power output to compensate for faint brightness and ridiculously little pixel lit time, which results in terrible eye strain. One possible solution is to increase persistence time somehow. At display frequencies of 120 Hz I think it can go the same way as regular CRT - a continious ray that scans through the screen.

    VR revolution will drive a incredible tech innovation wave in OLED technology.
    OVR will no longe nee smartphone panels an gets custom panels.......
    Display engineers only goal will be to achieve human resoluton for VR.
    Super certain!

    8k screens would be enough, and maybe for hardcore simulation applications (military, etc.) it may need 12k screens.

    I wonder if they can make BIGGER displays with similar pixel density? :)

    they use monocristallin silicon. If you look into a SSD and see how many monocristallin chips you can buy for 100$ i could well imagine it.

    Very nice, if this is a legitimate, released-to-market product that has come out of the lab and is actually being used. Then I stand corrected from the original post, perhaps samsung is not the leader in OLED technology development.

    Resolutions of that density would easily afford 12K + panels. However there has been no news or development from that company in over a year. Seems a bit odd?

    Hope im wrong :twisted:

    Because its more a very big research lab. But products actually go into the markt released by different companies.

    Thats fine,

    But it doesn't exactly prove that MicroOled panels have come out of the lab / manufactured or been supplied.

    also With a max brightness of 250Cd/m2 .... once low persistance is activated it could be a very dim display?

    http://www.tested.com/tech/smartphones/458384-samsung-galaxy-note-3s-diamond-sub-pixels-mask-pentiles-weakness/

    DisplayMate's latest investigation into mobile display technology reveals that Samsung's Galaxy Note 3 has one hell of a screen. Not only is the resolution doubled, from 720p to 1080p, but it's "the best performing OLED display to date across the board, including picture quality and color accuracy." More importantly, the Note 3's brightness maxes out at an incredibly bright 660 cd/m2, much higher than the Galaxy S 4's 475 cd/m2 and the iPhone 5's 556 cd/m2.

    i think we are talking here about 5 -10 years in the future when this tech will be applied.
